TS-Optics 50 mm right-angle finder scope with 90° Amici prism and 1.25" helical focuser
The TSFRE50 is more than just a finder. The fine 2-element lens with 50 mm diameter shows many hundred deep-sky objects. But the finder can also be used as guiding scope, together with specific autoguiders.
Eyepieces and autoguiders
Quality processing of metal for maximum stability
Good 2-element lens, multi-coated
Focusing by rotating the eyepiece side of the 1.25" helical focuser
Solid clamping through compression ring
Upright and non-mirrored image through the 90° Amici prism
The insight can be rotated to the wanted direction
The adjustable tube rings have metal screws with plastic tips to avoid scratches on the tube
The finder scope fits to standard finder shoes like the ones used by Skywatcher, Celestron, GSO, etc.
The focus of the finder is approx. 5 mm above the 1.25" receptacle of the focuser. That is enough for many eyepieces like Plössl eyepieces.
The finder is also suitable for autoguiding, but the autoguider must have a 1.25" housing, otherwise you will not reach the focus.
